Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

This need for consensus is absurd and unrealistic. There will always be some countries that put their interest above humanity.

Time to form an alliance of the willing and get on with it.

Countries meeting in Brazil for two weeks could manage only a voluntary agreement to begin discussions on a roadmap to an eventual phase-out of fossil fuels

Wow. An agreement to someday start talking about the beginnings of an agreement. "Inches" might be an overstatement.

Yeah, COP can only act by consensus, so the fossil fuels industry buys their way into national delegations, and blocks anything meaningful.

I don't know. I've recently read that 2024 we've globally emitted more than ever with a growth larger than ever. And that we're on path to emit more than that in 2025. That, to my uneducated ass, sounds more like we would be still accelerating, instead of coming to a halt.

Countries agreed to talk about talking about a plan for a fossil fuels phase out. Which is more than has happened before.

Its nowhere near where things need to be.

Thanks for the laugh!

But are you sure they haven't just agreed to talk about talking about talking about a concept of a plan?

agree to talk about concept of a concept of a plan(which being a research study thats already been done hundred times over to ascertain the increase likelyhood of remediation), thats has been the go-to for countries.

deforestation and mining minerals is one of the biggest contributers to increase in co2 as well. plus the hordes of rare and endangered plants/animals, its going to be oops we shouldve done this liek 20 years ago, in a book.
